Both dramas are set in Japan (even if Pandora's Box is a cdrama).
Both dramas are short and weird. With Pandora's Box, the weirdness comes from the sci-fi elements and the plot. With Yamaneko, the weirdness mostly comes from the characters.
Both dramas have a similar kind of surprise villain.
These dramas are very different in many ways, but I did think of Yamaneko a few times while I was watching Pandora's Box.
